DESCRIPTION (provided by applicant): The long-term goals of the present proposal are to develop individualized, efficient and effective training protocols and materials to maximize cochlear implant patient performance in real-world listening conditions. We hypothesize that targeted contrast training can greatly improve cochlear implant patients' performance for a variety of simulated real-world listening conditions, and that individualized training protocols and materials may be necessary to maximize training outcomes. We further hypothesize that passive learning may not allow cochlear implant patients to receive the full benefit of advanced coding strategies, and that targeted auditory training may help patients access the additional cues provided by novel processing schemes. There are three specific aims in the proposed research. First, we propose to measure the benefits of auditory training in simulated real-world listening conditions, including speech perception in noise, speech perception via telephone, and music perception. Second, we propose to develop individualized, efficient and effective training protocols and materials to maximize training outcomes. Third, we propose to quantify interactions between auditory training and changes to speech processor parameters. While the proposed experiments will evaluate different aspects of auditory training somewhat independently, there are areas of overlapping consideration that may be combined to advance auditory rehabilitation techniques for cochlear implant patients. These proposed experiments have great theoretical significance, as the results will shed light on auditory plasticity in electric hearing and the importance of training when evaluating experimental speech processor parameters. The experiments have even greater clinical significance, as the results will provide strong evidence of the benefits of auditory training, hopefully leading to affordable, efficient and effective rehabilitation that cochlear implant patients can perform at home, using personal computers. We expect that these training approaches, if successful in real-world simulations, will generalize to improved performance outside the lab. As recent advances in implant technology seem to be reaching the point of diminishing returns, auditory training may provide the most cost-effective approach for cochlear implant patients to maximize the benefit of the implant device.

描述(由申请人提供)：本提案的长期目标是开发个性化、高效和有效的培训方案和材料，以最大限度地提高人工耳蜗术后患者在真实世界听力条件下的表现。我们假设，有针对性的对比训练可以极大地提高人工耳蜗植入患者在各种模拟真实世界听力条件下的表现，个性化的训练方案和材料可能是必要的，以使训练结果最大化。我们进一步假设，被动学习可能不会让人工耳蜗植入患者获得高级编码策略的全部好处，而有针对性的听觉训练可能会帮助患者获得由新的处理方案提供的额外线索。这项研究有三个具体目标。首先，我们建议在模拟的真实世界听力条件下衡量听觉训练的好处，包括在噪音中的言语感知，通过电话的言语感知，以及音乐感知。第二，我们建议制定个性化、高效和有效的培训方案和材料，以最大限度地提高培训成果。第三，我们建议量化听觉训练和语音处理器参数变化之间的交互作用。虽然拟议的实验将在一定程度上独立地评估听觉训练的不同方面，但也有一些重叠的考虑领域可以结合起来，以促进人工耳蜗植入患者的听觉康复技术。这些实验具有重大的理论意义，因为这些结果将有助于阐明电听力中的听觉可塑性，以及在评估实验语音处理器参数时训练的重要性。这些实验具有更大的临床意义，因为结果将提供强有力的证据，证明听觉训练的好处，有望导致负担得起的、高效和有效的康复，人工耳蜗植入患者可以在家里使用个人电脑进行康复。我们预计，如果这些培训方法在真实世界的模拟中取得成功，将普遍提高实验室外的性能。随着最近植入物技术的进步似乎达到了回报递减的地步，听觉训练可能会为人工耳蜗术患者提供最具成本效益的方法，以最大化植入物装置的好处。
